I would see if it will run first, before you pull it...
But you will definately need to change the oil, and absolutely
must drain all of the gas. Including changing the fuel filter, and all of the fuel in the lines. Hopefully the injectors haven't bled off to let that gas gum up there too.
Fuel starts to die after a couple of weeks, give it months or years and it is varnish. You do not want pump even a quart of varnish through any part of you injection system.
I would drain the gas at the rail, by putting a hose on the supply line, turn on ignition, and empty the tank. Fully charge the battery, EFI, likes a full battery.
Good luck, if it ran before... It should start!
